Studies were carried out on integrated management of sugarcane stem borer, (Chilo infuscatellus) in the Punjab, Pakistan during 2008-09. The objectives of the studies to screen out the comparatively resistant varieties and also to find out the impact of abiotic factors. The use of chemical, biological, cultural, mechanical controls and their integration were also tested after 10, 15 and 20 days intervals. Fifteen varieties were tested during 2008 and the minimum infestation was recorded in US-718 (14.45%), which was statistically at par with those of US-312 (14.80%), CPF-246 (14.90%) and significantly different from varieties US-4191, US-676, US-133, US-824, CPF-234 and CPF-237 that showed 15.02, 15.28, 15.72, 15.83, 15.90 and 15.95% infestation. From the preliminary screening, US-718 and US-312 having least infestation with 14.45% and four varieties US-4191, US-678, US-133, US-824 showing intermediate infestation (15.02%, 15.28%, 15.72%, 15.83%) and three varieties US-824, CPF-234 and CPF-237 having maximum infestation 15.83, 15.90 and 15.95% were selected. The impact of abiotic factors indicated that maximum temperature did not affect the infestation level significantly whereas the minimum temperature showed a significant and positive correlation to infestation with r-values 1.00, 0.065, 1.00 and 0.036 during 2008-09 respectively. The relative humidity showed significant correlation having positive response to infestation with r-values of 0.637 and 0.520 during 2008-09 collectively. The effect of rainfall on the stem borer infestation was highly significant with r - values of 0770 and 0.781 during 2008-09 cumulatively. The variety US-133 contained maximum nitrogen and fat contents, which were calculated to be 1.147% and 2.20%, respectively. The highest recovery was recorded to be 11.74% in variety US-312, whereas the lowest in SPF-234 which was 8.12%. Plant girth and leaf area were comparatively higher in US-824 SPF-234 with 5.47 cm2 and 4.66 cm2 as compared with other varieties. The CPF-246 possessed maximum Phosphorous quantity (0.244%), whereas minimum contents were found in US-778 (0.191%). The concentration of Potassium was comparatively higher in SPF-234 (0.243%) and maximum quantity of Calcium was calculated in variety US-1491 (0.249%). Maximum Magnesium-contents were found in variety SPF-234, which were calculated to be 0.240% and maximum Copper was recorded in variety CPF-237 (4.25ppm). The lowest Ferrous was recorded in US-312 with 31.70ppm and minimum Manganese was recorded in US-312 (30.73ppm) while maximum Zinc present in SPF-234 with 22.60ppm. The results of insecticides against the sugarcane stem showed minimum infestation by Furadan followed by Thimet, Padan and Monomehypo with which showed 10.22%, 11.35%, 12.45% and 13.84% respectively, after 15 days interval. In case of cultural and mechanical control, the minimum infestation (12.91%) was recorded by using Trash mulching while in case of biological control, minimum infestation (9.31%) was recorder by using 72000 Trichogramma eggs after 10 days interval while the integration of Trichogramma cards, detrashing and light traps showed minimum infestation (8.71%) after 10 days interval.

کیوں اس طرح کی صورتِ حالات ہو گئی

کیوں اس طرح کی صورتِ حالات ہو گئی
مشکل ہی دوستوں سے ملاقات ہو گئی

زلفیں ہٹیں جو رُخ سے تو روشن ہوا تھا دن
واپس ہوئیں تو دیکھیے پھر رات ہو گئی

اک بے وفا کی یاد بھلانے کو زندگی
افسوس یہ کہ نذرِ خرابات ہو گئی

سارے جہاں نشاط کے جب اس کے ہو گئے
پھر رنج و غم کی دنیا مرے ساتھ ہو گئی

تائبؔ کچھ اس طرح سے میں رویا ہوں رات بھر
لگتا ہے جیسے شہر میں برسات ہو گئی

Mothers-in-law as Key Influencers: Study on a Radio Drama Intervention to improve Maternal and Child Health in Pakistan

Mothers-in-law play an integral role in promoting maternal and child health practices in rural Pakistan. This study discusses the design, implementation, and evaluation of a 25- episode radio drama featuring the mother-in-law as the primary influencer for maternal and child health practices. The radio drama was designed after an extensive pre-drama audience research comprising of 10 focus groups, and 14 in-depth interviews in Bagh and Mansehra. Post-drama evaluation comprised two focus groups in the target areas. The endline evaluation found that viewership of the drama improved communication between people of all age groups and social roles without offending their dignity, intelligence, and sense of tradition. Additionally, the findings showed that the audience demonstrated improvement in knowledge about danger signs for mother and child, as well as positive attitudes to seeking timely service from a trained healthcare provider. The study makes a contribution to existing health communication campaigns by introducing a culture-centric approach, through radio dramas, to influence mothers-inlaw and consequently impact maternal and child health practices.

Genetics of Physio-Agronomic Traits in Maize under Water Deficit Conditions

Fifty inbred lines of maize acquired from various sources, were screened in the wirehouse for seedling traits under both normal and water deficit conditions. Six inbred lines were earmarked on the basis of various agronomic and physiological traits under water deficit condition. The inbred lines were sown in the field for making all possible crosses in diallel mating fashion. The F 1 crosses and their reciprocals alongwith the parents were sown in the field under normal and water stress environment using Randomized Complete Block Design in three replications. Normal irrigations were applied to one set of experiment, whereas 50% of the normal irrigation was applied to water stress experiment. Data for various morpho- physiological characters were recorded at different growth stages of the crop and then subjected to statistical analysis. Co-efficient of variability was found to be greater under water stress than under normal condition for majority of the seedling traits. Significant mean squares for all the parameters under normal and moisture deficit conditions depicted the presence of considerable genetic variability. Scaling tests were performed to check the adequacy of the data for analyzing additive-dominance model. The results showed that additive-dominance model was fully adequate for the traits like kernels per row, 100-kernel weight, grain yield per plant, cell membrane thermostability, stomatal conductance and canopy temperature under normal condition while plant height, ear height, days to silking, kernels per ear, 100-kernel weight, grain yield per plant, leaf temperature and canopy temperature depression under water stress condition. The data were partially adequate for the traits like ears per plant, days to tasselling, anthesis-silking interval, kernels per row, cell membrane thermostability and stomatal conductance under moisture deficit condition. Additive gene action for number of days to silking under normal water condition changed to non-additive gene action under water deficit condition. All other traits exhibited additive gene action under both conditions. Heritability estimates for yield related traits revealed maximum ability to transfer the desirable genes to the next generation. Estimation of components of variation exhibited greater estimates for GCA variance ( б 2 g) than SCA variance ( б 2 s) for majority of the traits under both conditions depicting the predominant role of additive genetic component except for days to silking and number of kernels per row under water deficit condition which displayed greater SCA variance ( б 2 s) than GCA variance ( б 2 g). Under water stress condition, the best performing crosses were NCIL-20-20 x D-109, NCIL-20-20 x OH-8 and D-114 x NCIL-20-20 and their reciprocals. Inbred lines NCIL-20-20, D-157 and D-114 proved to be high yielder parents under both normal and moisture deficit conditions. The information regarding results obtained during the current study may be used to evolve better parental inbred lines for developing various cross combinations which will be helpfull in maintaining yield sustainability in water deficit areas.
